To all 'whom t may concern.'

Be it known that JOHN VINCENT Meanies, a citizen of the Commonwealth of Australia, and resident of 48 Cawlwell Street, Malvern, near Melbourne,'in the Stateof Victoria, Commonwealth of Australia, has invented a certain new and useful Means Jfor Concrete Construction, ot which the following is a specification.

The invention relates to a simple and strong construction of concrete walls ot which each web is made in one integral part.

The invention comprises (a) The making of tapered coreboxes of wood, metal or the like of any desired dimensions, and having the outer faces, if made of other material than metal, or metal rsheeting to allow of the easy withdrawal of the coreboxes after a course of wall is com pleted.

(b) The making of inner and outer Jforms of similar material to lthat of the coreboxes, of any desired dimensions, but the use of metal sheeting is discretionary. Very thin pieces of bevelled wood or iron or the like are fixed at intervals to the inner faces of the outer forms throughout their height. These will leave grooves in the outer Jface ot the wall, when the forms are removed, which grooves will allow for the action of changes of temperature of the walls.

(c) The making of tie-holders specially shaped pieces of wood or any suitable material-which are placed between the ends of succeeding coreboxes, at the corners, at the door and window reveals and in the main wall wherever ties are intended to be placed. These hold iron or steel ties in position until the concrete is placed round the ties, and are left there till the concrete is sufficiently set Jfor their removal.

(d) The using of the appliances men-l tioned under headings (a), (li) and (c) above as follows The coreboxes are placed along the foundations between the inner and outer forms, the faces ot other and the corebox, and at the desired distance from the corebox. The Jforms are connected to the corebox and tov each other by rbolts extending through Jfrom outside to. inside of the combination. The bolts taper so that they may be easily withdrawnwhen necessary. Devices as shown in Figures 11, 12 and 12a, may be used in lieu of bolts.

`These devices will be explained in detail at which will be parallel to each.

.coreboxes, inner and outer forms, tie-holders, bolts or devices in lieu of bolts-is allowed to remain until 1t is desired to remove it.

(c) The use of contrivance shown in Figure 14 for the purpose of strengthening the 1 lower portion of a wall or' considerable height. This contrivance will be explained later.

The invention will now be described in detail, and for that purpose reference will be made to accompanying diagrams wherein Figure l is a plan of the wall embodying the invention.

the wall. Attached to this plate 14 are cleats 14?. The inner and outer forms 2 and 3 lie between these cleats 14a and the upper part of the wall last completed and are firmly held in position by the cleats.

When the coreboxes 1 and inner 3 and outer 2 forms are set on the foundations and secured to one another, the concrete is poured into the cavities 9 and 10 between the inner and outer forms 3 and 2 and the coreboxes 1 and when the concrete is set sufliciently the inner and outer forms, tie-holders and coreboxes are removed.

For the remaining course, the same method of erecting appliances and filling cavities is adopted, but to retain the appliances in their new correct position, ties of iron or steel are placed across the cavity, their ends resting on the webs of the course last completed. Slots 1e in the bottom edges of the coreboxes receive the ties and cause the coreboxes to rest on them.

Figure 14 shows a contrivance for strengthening the lower parts of a wall of considerable height. The members 15 are made of iron or steel of any suitable dimensions, bevelled as shown and are iirnily connected by iron or steel rods 15a -of suitable lengths and diameter. The parts 15c are inserted in holes in members 15 so that the shoulders 15d rest firmly against the inner faces of the members 15, and the ends of the parts 15c projecting beyond the outer faces of members 15 are burred so that the rods 15a may not be withdrawn. These rods 15a are preferably stepped from each other along the vertically disposed members 15 in 4zig-zag fashio-n, or two or more may be in line and the next two or more out of vertical line as illustrated.

What I claim as my invention and desire to secure by Letters Patent is 1. In concrete construction, coreboxes placed along foundations between inner and outer forms the faces of which are parallel to each other and the corebox which is distanced therefrom connecting the forms to the corebox and to each other by fastening devices extending through from the outside to the inside of the said parts, means for maintaining the coreboxes and wall forms in their correct position comprising a template having a inortise bevelledon one side to receive a squared piece of material and a wedge placed on the top edges of the forms and coreboxes so that one of the forms and its stud fits in a recess between shoulders, the corebox fitting in a recess between shoulders, a squared piece of material in the mortise and lying along the vertical face of the other form, and a wedge inserted in the remainder of the mortise.

2. In concrete construction coreboxes provided with tapered studs to which facings are affixed, holes at various points to admit tapering bolts, notches in the bottom edges of the corebox to receive and rest upon ties during the construction of all wall courses except the first one, substantially as described.

3. In concrete construction, corner tieholders formed in two parts and bevelled and shaped, having abutting faces which meet at such an angle that the horizontal axes of the holders make right angles with each other.

4. In concrete construction, bevel tie-holders each constructed and placed so as to lie between parts of a corebox, another part being set against a jamb lining board as and for the purposes specified.
